DECORATING GLASS, 81,0.

SEECIFILGATION forming part of Letters Patent No. 690,889, dated January'7, 1902.

Application filed June 8,1901. Serial No. 63,862. (No specimens.)

To coZZ whom, it may concern:

Be it known that I, HARRY LAWRENCE VON BONHORST, of the city of LosAngeles, in the county of Los Angeles and State of California, haveinvented certain new and useful Improvements in Decorating Glass andother Transparent Substances, so as to Imitate Ornamental Stone, to beused in buildings and in the equipment of buildingssuch asWainscot-panels,do0r-panels, railway-carriage panels, ships panels, andother like uses-of which the following is a full, clear, and exactdescription or specification.

My said invention, which relates to the decorating of glass so that theglass when so decorated has or may have the appearance of ornamentalstone-such as onyx, agate, marble, granite, or other analogousornamental stonesconsists in treating the pieces of glass or othertransparent material to be decorated for such uses and for analogoususes hereinbefore described as follows:

A flat receptacle of slaked lime or whiting is prepared by placing anyrequired depth of such slaked lime or whiting into a flat box or vessel,the slaked lime or whiting being mixed with water to render the lime orwhiting a semifiuid body, and upon the upper level or smooth surface ofthis said semifluid body there is dropped oil-paint of the requisitecolors, quantities, and consistency and in such positions upon the flatlevel surface of the semifluid body of lime or whiting and water that itshall in itself imitate the ornamental colors and relative positions ofthe ornamental colors in the stone sought to be imitated. In this mannerthe upper surface of the semifluid lime or whiting and water becomesinterspersed in the required positions with drops of the paint of therequisite color and in the requisite positions to produce the imitativeeffect, which effect is ultimately reached by blending or comminglingtogether to any required extent the drops of paint with any suitablemanually-operated instrument, such as a spatula. When the colors havethus been dropped and mixed or blended and commingled in the semifluidpowdered lime or whiting and water, then the sheet of glass,

which has previously been wiped clean, is laid directly on the semitluidmaterial, the effect of which laying on of the glass is to cause themixed or commingled paint to adhere to the lower surface thereof, so asto admit of the sheet of glass being lifted out of the bath with the commingled or blended paint adherin g thereto in the required position inimitation of the stone to be imitatively represented thereby. In thiscondition the commingled or blended paint is allowed to dry on the undersurface of the glass, and then, but not until then, any powdered lime orwhiting which may adhere to the glass is washed off from the glass,thereby leaving those portions of the surface of the glass which are notcovered by paint clear and transparent. The sheet of glass with paintthus dried on it and with the lime or whiting washed off it is then inthe condition for receiving the ground or basic color of the stone to beimitated, and in order to cover these intermediate surfaces or spaces ofthe transparent glass or other material with the color necessary toconstitute the ground or basic color of the stone imitated the entiresurface of the glass upon whichlthe imitative coloring of the ornamentalstone has been fixed by drying is then wholly painted over withoil-paint or any color requisite to produce the ground or basiccoloring, which then causes the front unpainted surface of the glass toappear smooth and polished, in imitation of the ornamental stoneintended to be imitated or represented.

In order to make it perfectly certain that the entire surface of theglass is completely covered with oil-paint, there may be one or morecoatings of the ground or basic color painted upon the back of the sheetof glass, and to prevent the imitative surfaces from being disturbed byfriction, abrasion, or scratches, or rubbing a coating of sand or otherfine granulated material may be distributed over the ground or basiccolor and remain permanently attached thereto, being allowed to drythereon.

It is to be understood that my invention may be applied to panels orwainscoting of every kind or description, so that my inventionnecessarily has a very large range of applicability in all cases Wheresurfaces of buildings or of furniture or of doors or windowcasings orother parts of buildings have to be decorated with ornamental stone, and

'my invention has the advantage over using actual stone that it iscapable of producing very exact imitative effects of such stone at avery considerable reduction in the price of the said material used fordecorative purposes. The other advantages which result from the use ofthese decorative panels are so obvious to any decorator or constructorof ornamental buildings that it is altogether unnecessary to refer tothem in this specification.

What I claim as myinvention consists as follows:

The ornamenting of plates or sheets of glass or other transparentmaterial by means of paint dropped into a semifluid body of slaked lime,said paint being mixed or commingled in any desired proportions ofcoloring or imitative effect of color in ornamental stones,

after which said paint or imitative coloring is caused to adhere to thesurface of a plate or sheet of glass in the imitation desired, andwhereon said commingled coloring is allowed to dry; and after beingdried, the whole is washed with water, whereby any slaked lime V isremoved from the intermediate spaces of the colored imitation in thepaint blended and adhering to the inner surface of the glass whichintermediate surfaces are-then covered by a ground or basic coloringcaused to adhere thereto by drying thereon, the said inner surface beingafterward finely coated with sand or equivalent material, for protectingit in the manner and for the purposes hereinbefore described.

In testimony whereof I, HARRY LAWRENCE VON BONHORST, have hereunto setmy hand and seal, this 16th day of March, 1901, in the presence of twosubscribing witnesses.
